The quantum geometric phase has long been viewed as an interesting, but somewhat mysterious, feature of quantum mechanics. However, the ability to harness and control geometric phase in individual quantum systems may drive the development of a new class of quantum technologies. This project aims to measure, for the first time, geometric phase due to the macroscopic motion of an atom-scale quantum system, specifically in rotating nitrogen-vacancy defects in diamond. It is expected that these proof-of-principle measurements will provide the basis for the future development and design of new nano-scale quantum gyroscopes and set the foundations for using nano-diamonds as rotational diagnostic tools in a range of important nanoscopic systems.Read moreRead less

This project aims to provide new understanding of information and security in higher-dimensional systems, and to exploit this to deliver a secure, high-capacity, quantum image transfer protocol for quantum communication and quantum cryptography technologies. In quantum physics, the best possible knowledge of a whole does not include the best possible knowledge of the parts: not knowing any of the letters of a word does not imply not knowing what the word is. This project aims to examine the high-dimensional transverse spatial modes of photon to show that the converse is also true: not knowing the word does not imply not knowing any of the letters. Project outcomes may have applications in remote sensing and surveillance.Read moreRead less

This project aims to extend the density and coherence of qubits stored in superconducting-based quantum processors, by exploring the concept of hybrid quantum systems. Quantum computers are expected to impact a diverse range of sectors, from medicine to national security. This project seeks to develop an enabling technology, a memory, for scaling a quantum computer constructed from superconducting circuits, such as those being developed in commercial laboratories. Such scaling would improve the capacity of these processors to tackle complex problems. The quantum technology developed in this project will have immediate application in transforming a widely-used technique for studying the nanoscale structure of biomolecules - distance measurements in electron spin resonance spectroscopy.Read moreRead less

This project aims to integrate quantum hyperpolarisation technology into state-of-the-art nuclear magnetic resonance (NMR) systems, potentially boosting the signal by several orders of magnitude. Understanding the structure and function of membrane bound peptides and proteins in cells in their native environments is critical in drug development. However, studying these biomolecules by conventional NMR under ambient conditions is challenging due to sensitivity limitations. The technology developed by this project will be a significant step forward in NMR and the new science enabled may have far reaching consequences for the study of peptides and proteins of live cells for the development of new drugs and anti-biotics, with direct societal benefits and flow-on economic benefits.Read moreRead less

This project will create the experimental tools to fully control the motion of a mechanical oscillator at the single-quanta level, opening a rich avenue for fundamental research and the development of quantum physics enhanced applications. This project will prepare a quantum state of a macroscopic mechanical resonator exhibiting quantum interference fringes at at an unprecedented mass scale. The observation of these fringes will enable the study of the intricacies of quantum decoherence and ultimately even probe quantum gravitational phenomena. To achieve these goals it will employ micro-scale optical resonators fabricated by established techniques, that also provide the ideal platform for scalable mechanical-oscillator-based quantum information applications.Read moreRead less

This project aims to develop an artificial atom in diamond that can connect to other nodes in a network. Network connectivity and data distribution are increasingly important in today's information economy. Tiny glowing artificial atoms in coloured diamonds can receive, store and send information in a network using laser light and microwaves. Because they work at the level of individual atoms and photons, they can use quantum-weirdness to achieve feats impossible even for supercomputers on the classical internet. The proposed device is expected to make it easier to construct technologies that move beyond the limitations of existing infrastructure thus satisfying the unmet core requirements for a quantum network.Read moreRead less
